Coach of the Washington State University football team joined the Cougars after nine years at Texas Tech.
Known for his fiery temper during his days at Texas Tech, he spent one memorable game against rival Texas railing against the officials, for which he was a fined a record $10,000.
He was fired from Texas Tech amidst much acrimony and a wrongful termination lawsuit, and then signed on with Washington State to coach in 2012.
He was born in Susanville, California, part of The Church of Jesus Christ of Latter-day Saints.
Friday Night Lights creator Peter Berg featured him in a cameo in one episode, and hinted he would write a movie inspired by Leach's firing from Texas Tech.
